Boron Nitride

Pyroflux offers a complete range of high-performance hexagonal boron nitride (h‑BN) products tailored for metallurgical, forging, casting, extrusion, brazing, and die protection applications. Our BN product line includes powders, suspensions, aerosol sprays, wax candles, and specialty coatings formulated for high-temperature and non-stick performance in demanding industrial environments.

They manufacture an array of hexagonal boron nitride products: 

• Pure hBN powder (3 microns – 50 microns / 99% + Purity)
• hBN suspensions / pastes in water / solvent / oil
• hBN based release agents & lubricants (in acqueous / alcohol / oil bases)
• hBN Aerosol sprays
• Custom, user specific hBN formulations

Applications:

• Glass Forming
• Vacuum Metallization Process 
• Aluminum brazing & flux shielding (KAlF₄, KBF₄, etc.)
• Aluminum & copper extrusion
• Die casting of non-ferrous metals
• Cold / Hot Forging
• In Plastics (polymers) to improve thermal properties — particularly thermal conductivity
• Furnace part protection (SS frames, fixtures, tools)
• Electrical insulation in thermal systems
• Release agents in high-temp forming operations

HBN is used in various applications, including:

Electronics: hBN is used as an insulator to isolate devices from the environment
Optical devices: hBN is used as a waveguide
Quantum photonic devices: hBN is used in quantum photonic devices 
Lubrication: hBN powder can be dispersed in lubricating oil, grease, and water
Glass manufacturing: hBN powder is used in the glass manufacturing process
Aeronautics and space: hBN powder is used in aeronautic and space applications
